Abstract
Description
-
- 2) as a programmable dispersion-based system, using a spatial light modulator consisting of an array of individually addressable devices.
-
- a) a light source for directing light toward the object;
- b) an input optics section for gathering light to obtain a multispectral image bearing light;
- c) a programmable spectral filter that conditions the multispectral image bearing light according to a predetermined spectral transmission function;
- d) a detector array in the path of the conditioned multispectral image bearing light and providing a corresponding output signal; and,
- e) a control logic processor in communication with the spatial light modulator for modulating addressable areas of the spatial light modulator to provide the spectral transmission function thereby.
-
- (i) wavelength of one or more filter passbands, usually specified using the center frequency of the passband;
- (ii) number of wavelength bands transmitted, allowing multiple discrete wavelength bands to be provided at the same time;
- (iii) bandwidth of passbands; and
- (iv) characteristic shape of the spectral transmission function, controlling transmittance at each wavelength within a passband, effectively providing continuously variable transmission over a selected range of wavelengths.
